I'm building the tower version of "Dr. K's MTM" and I don't know how much lining I should put in. Also, I'm using old memory foam from a mattress, I figure it is dense enough and stable enough not to break down and crumble over the years. If there's any reason I should not be using memory...

Since Vicoustic discontinued their original Wavewood panel for the “Lite” version, I set to work creating my own. I got a CAD drawing of the original MLS slot pattern and sent it to a woodworking company to cut and finish. I then sourced the same density foam as the original, but twice as...

Assembling my theater - there’s so much echo in the room, really messing with the sound. I know I need a mix of diffusion and absorption. Is there a thread that teaches how to build panels, how many to use, and where to place them? Any subject matter experts here?

5 tube traps I built to tame the bass frequency of my room. Like the ASC traps, have of their surface is lined with a sheet of plastic lining, to keep mid and high frequencies from getting absorbed. Built from fiberglass pipe fittings, with oak end pieces to seal them. Works great for handling...
